Abstract (en)

[origin: WO2019068935A1] The present invention relates to dye molecules and to staining compositions comprising said dye molecules that are particularly suitable for selectively staining biological substrates, such as structures in the posterior eye segment and proteins. Said dye molecules may be used in ophthalmic surgery to help the surgeon to visualize structures in the posterior eye structures as well as in protein assays to determine one or more analytical parameter of a protein. The dye molecules have the following structure (I) wherein X represents an organic or inorganic cation; and R1 represents a substituted or unsubstituted benzyl group. The present invention relates also to a new method for synthetizing dye molecules.
